[0063] The present invention will be further described below in conjunction with the accompanying drawings.

[0064] like Figure 1-19B As shown, according to the first aspect of the present invention, the present invention provides a bathing bed for intelligently washing the back, comprising an outer frame 1, at least four bed board mechanisms 2 and a washing mechanism 3. The outer frame 1 is used as the overall support and force-bearing structure of the bathing bed.

[0065] The upper surface of the bed board mechanism 2 is used to support the user. Specifically, each bed board mechanism 2 includes a flip plate 21, one side of which is rotatably connected to the outer frame 1, and the flip plate 21 is constructed to be able to rotate to a horizontal closed position or a vertical open position.

[0066] like Figure 1 and Figure 2 As shown, an example is shown in which the number of the bed board mechanisms 2 is four, and the flip plates of each bed board mechanism 2 are respectively a first flip plate 21a, a second flip plate 21b, a third flip plate 21c and a fourth flip plate 21d. Figure 1FIG. 2 shows a state where the four flip plates are all in a horizontal closed position. The first flip plate 21a and the second flip plate 21b are arranged in a width direction of the outer frame 1 (eg Figure 1 The third flip plate 21c and the fourth flip plate 21d are arranged side by side in the width direction of the outer frame 1 (as shown in the Y-axis direction), and the opening mode of the two is a split opening mode; the third flip plate 21c and the fourth flip plate 21d are arranged side by side in the width direction of the outer frame 1 (as shown in the Y-axis direction). Figure 1 The first flip plate 21a and the fourth flip plate 21d are arranged side by side in the length direction of the outer frame 1 (as shown in the Y-axis direction), and the opening mode of the two is a split opening mode; Figure 1 The second flip plate 21b and the third flip plate 21c are arranged side by side in the length direction of the outer frame 1 (as shown in the X-axis direction), and the opening method of the two is the same direction of opening; Figure 1 The two are arranged side by side in the X-axis direction as shown, and the opening method of the two is the same direction opening method.

[0067] Please combine Fig. 6A , Figure 6B and Figure 6C In order to illustrate the cleaning mechanism 3, all the flip plates 21 are rotated to the vertical open position. It should be noted that in actual use, not all the flip plates 21 are rotated to the vertical open position. The cleaning mechanism 3 can be moved to the cleaning position (such as Fig. 9 and Fig.10 As shown), the back of the user of the bed board mechanism 2 can be cleaned, and after the cleaning is completed, it returns to the storage position (as shown). Figure 7 and Figure 8 The cleaning mechanism 3 is movably arranged in the outer frame 1, and the cleaning mechanism 3 is configured such that when the flip plate 21 is in the vertical open position, the cleaning mechanism 3 moves to the cleaning position corresponding to the flip plate 21; and when the cleaning mechanism 3 moves to the storage position, the flip plate 21 rotates to the horizontal closed position.

[0068] Specifically, the outer frame 1 includes a support frame 10 (such as Figure 3 and Figure 5 As shown) and a first beam 11 and a second beam 12 parallel to each other, wherein the first beam 11 can be integrated into the support frame 10, that is, the first beam 11 can be used as a support beam of the support frame 10. Figure 2 and Figure 3 As shown, the first beam 11 and the second beam 12 are both along the length direction of the outer frame 1 (i.e. Figure 3 The second beam 12 extends in the X-axis direction as shown, the second beam 12 is located at the inner side of the first beam 11, and is spaced apart from the first beam 11, that is, there is a gap between the second beam 12 and the first beam 11.

[0069] Both ends of the flip plate 21 are rotatably connected to the second beam 12 respectively. The flip plate 21 is constructed to be able to rotate upward or downward with the connection between the flip plate 21 and the second beam 12 as a pivot axis, and when the flip plate 21 rotates upward to a horizontal closed position, the upper surface of the flip plate 21 is flush with the first beam; when the flip plate 21 rotates downward to a vertical open position, the side of the flip plate 21 close to the first beam 11 rotates to the top of the first beam 11 and the side of the flip plate 21 away from the first beam 11 rotates to the bottom of the first beam 11.

[0070] Therefore, it can be known that the second beam 12 can serve as a rotation fulcrum of the flip plate 21 .

[0071] like Figure 2 , Figure 4 and Figure 5 As shown, the two ends of the first flip plate 21a are respectively at the pivot axis a 1 The second flip plate 21b is connected to the second beam 12 at the pivot axis a. 2 (not shown) is connected to the second beam 12 for rotation, and the two ends of the third flip plate 21c are respectively connected to the pivot axis a 3 The fourth flip plate 21d is rotatably connected to the second beam 12 at both ends of the fourth flip plate 21d. 4 In other words, the first flip plate 21a, the second flip plate 21b, the third flip plate 21c and the fourth flip plate 21d can be respectively connected to the second beam 12 at the pivot axis a. 1 , pivot axis a 2 , pivot axis a 3 and pivot axis a 4 The axis of rotation is rotated. Figure 4 As shown, the fourth flip plate 21d is pivoted to the pivot axis a 4 Rotate the axis downward to the vertical open position. Figure 2 As shown, the fourth flip plate 21d is pivoted by a pivot axis a 4 The swivel shaft is rotated upward to rotate to the horizontal closed position.

[0072] When one of the flip plates 21 is in a vertical open position, for example Figure 4 As shown, when the fourth flip plate 21d is rotated to the vertical open position, the fourth flip plate 21d no longer supports the user's back. In other words, the area on the user's back corresponding to the fourth flip plate 21d (e.g., the area on the user's back near the buttocks and right leg) can be exposed; or Figure 8As shown, when the third flip plate 21c rotates to the vertical open position, the third flip plate 21c no longer supports the user's back. In other words, the area on the user's back corresponding to the third flip plate 21c (for example, the area on the user's back near the buttocks and left leg) can be exposed, so the cleaning mechanism 3 can move the cleaning position corresponding to the fourth flip plate 21d or the cleaning position corresponding to the third flip plate 21c to clean the area on the user's back. It can be understood that at this time, the other three flip plates are all in a horizontal closed state, so they can also support the user, so there is no need to worry about the user being in danger of tipping over.

[0073] Please continue to see Figure 2 and Figure 4 The bed board mechanism 2 further includes an arc-shaped connecting plate 22 and a flipping driver 23. The arc-shaped connecting plate 22 is located between the first beam 11 and the second beam 12, and one end of the arc-shaped connecting plate 22 is rotationally connected to a side of the flipping plate 21 close to the first beam 11. The flipping driver 23 is fixedly arranged inside the outer frame 1 and rotationally connected to the other end of the arc-shaped connecting plate 22.

[0074] Among them, the arc-shaped connecting plate 22 is constructed to extend from between the first beam 11 and the second beam 12 of the outer frame 1 under the drive of the flip driver 23, so that the flip plate 21 rotates downward to a vertical open position; or to return from between the first beam 11 and the second beam 12 of the outer frame 1 under the drive of the flip driver 23, so that the flip plate 21 rotates upward to a horizontal closed position.

[0075] The arc-shaped connecting plates 22 and the flipping drivers 23 are arranged in one-to-one correspondence with the flipping plates 21 , that is, each flipping plate 21 is equipped with an arc-shaped connecting plate 22 and a flipping driver 23 .

[0076] like Figure 8 As shown, for the first flip plate 21a, the upper end of the arc-shaped connecting plate 22 is connected to the first flip plate 21a by the pivot axis a. 1 The arc-shaped connecting plate 22 is rotatably connected to the flip plate connecting plate 24 connected to the first flip plate 21a, and the lower end of the arc-shaped connecting plate 22 is connected to the first flip plate 21a by the pivot axis b. 1 Rotationally connected to the flip drive 23; Figure 2 and Figure 4 As shown, for the third flip plate 21c, the upper end of the arc-shaped connecting plate 22 is connected to the third flip plate 21c by the pivot axis a. 3 The arc-shaped connecting plate 22 is connected to the flip plate connecting plate 24 connected to the third flip plate 21c, and the lower end of the arc-shaped connecting plate 22 is connected to the flip plate connecting plate 24 through the pivot axis b. 3 For the fourth flip plate 21d, the upper end of the arc-shaped connecting plate 22 is connected to the turning drive 23; 4 The arc-shaped connecting plate 22 is rotatably connected to the flip plate connecting plate 24 connected to the fourth flip plate 21d, and the lower end of the arc-shaped connecting plate 22 is connected to the fourth flip plate 21d by the pivot axis b.3 Rotationally connected to the flip drive 23.

[0077] Therefore, it can be seen that for the second flip plate 21b, the upper end of the arc-shaped connecting plate 22 passes through the pivot axis a 2 The arc-shaped connecting plate 22 is connected to the flip plate connecting plate 24 connected to the second flip plate 21b, and the lower end of the arc-shaped connecting plate 22 is connected to the flip plate connecting plate 24 through the pivot axis b. 2 (not shown) is rotationally connected to the flip drive 23.

[0078] The flipping driver 23 may be, for example, an electric push rod or a hydraulic push rod, which can push and pull the arc-shaped connecting plate 22 to achieve the rotation of the flipping plate 21 .

[0079] Specifically, if Figure 2 and Figure 4 For example, when the fourth flip plate 21d needs to be rotated, the flip driver 23 corresponding to the fourth flip plate 21d extends, thereby pushing the arc-shaped connecting plate 22 connected thereto to extend from between the first beam 11 and the second beam 12, and the upper end of the arc-shaped connecting plate 22 and the fourth flip plate 21d are connected to each other by the pivot axis c. 4 The fourth flip plate 21d rotates relative to the rotation axis, and the fourth flip plate 21d rotates relative to the rotation axis a 4 The rotation axis rotates relative to the second beam 12, that is, the fourth flip plate 21d rotates clockwise from Figure 2 Rotate to the horizontal closed position shown Figure 4 Alternatively, for example, when the third flip plate 21c needs to be rotated, the flip driver 23 corresponding to the third flip plate 21c extends, thereby pushing the arc-shaped connecting plate 22 connected thereto to extend from between the first beam 11 and the second beam 12, and the upper end of the arc-shaped connecting plate 22 and the third flip plate 21c are pivoted about the pivot axis c 3 The third flip plate 21c rotates relative to the rotation axis. 3 The rotation axis rotates relative to the second beam 12, that is, the third flip plate 21c rotates counterclockwise from Figure 2 Rotate to the horizontal closed position shown Figure 8 The vertical open position shown. The opening and closing of the first flip plate 21a and the third flip plate 21c are similar, and will not be repeated here.

[0080] Please continue to see Figure 2 The arc-shaped connecting plate 22 is constructed as an arc-shaped structure protruding in a direction away from the second beam 12, wherein when the arc-shaped connecting plate 22 extends from or returns between the first beam 11 and the second beam 12 of the outer frame 1, the outer side of the arc-shaped connecting plate 22 maintains contact with the inner edge of the first beam 11.

[0081] As described above, there is a gap between the first beam 11 and the second beam 12, so the arc-shaped connecting plate 22 can move in the gap, so the second beam 12 can also play a role in constraining the movement trajectory of the arc-shaped connecting plate 22. The arc-shaped connecting plate 22 is constructed as an arc-shaped structure, and when it is extended or returned, its outer side can keep in contact with the inner edge of the first beam 11, thereby ensuring that the arc-shaped connecting plate 22 has a stable movement trajectory; and the arc-shaped connecting plate 22 can be rotated at a relatively uniform speed to avoid excessively fast rotation and causing back injuries to the user.

[0082] One of the flip plates 21 of each bed board mechanism 2 is in a vertical open position, and the other flip plates are in a horizontal closed position. As described above, since the flip plates 21 can support the back of the user when they are in the horizontal closed position, if all the flip plates 21 are rotated to the vertical open position, Fig. 6A As shown, the user will lose support and fall down at this time. Therefore, in order to avoid this situation, only one flip plate is in the vertical open position at a time during use, and the other flip plates are in the horizontal closed position at the same time.

[0083] like Figure 2 As shown, when the third flip plate 21c and the fourth flip plate 21d are in the horizontal closed position, the upper surfaces of both are flush with the upper surface of the first beam 11; it can be understood that when the first flip plate 21a and the second flip plate 21b are in the horizontal closed position, the upper surfaces of both are flush with the upper surface of the first beam 11; therefore, there is no protrusion on the surface of the entire bathing bed to avoid hurting the user.

[0084] like Figure 6C As shown, when the third flip plate 21c is in the vertical open position, since the third flip plate 21c rotates relative to the second beam 12, and the second beam 12 is located below the first beam 11 in the Z-axis direction, after the third flip plate 21c rotates, the side close to the first beam 11 rotates to the top of the first beam 11, and the side away from the first beam 11 rotates to the bottom of the first beam 11. Similarly, when the fourth flip plate 21d is in the vertical open position, since the fourth flip plate 21d rotates relative to the second beam 12, and the second beam 12 is located below the first beam 11 in the Z-axis direction, after the fourth flip plate 21d rotates, the side close to the first beam 11 rotates to the top of the first beam 11, and the side away from the first beam 11 rotates to the bottom of the first beam 11. The first flip plate 21a and the second flip plate 21b have similar effects.

[0085] It should be noted that Fig. 6A , Figure 6C and Figure 6CAlthough each flip plate 21 is in a vertical open position, it is only for illustrative purposes and is only for better showing the structure of the cleaning mechanism 3. In use, only one flip plate 21 is in a vertical open position, and the other three flip plates 21 are all in a horizontal closed position.

[0086] It can be understood that the purpose of setting multiple flip plates 21 in the present invention is that the multiple flip plates 21 can correspond to different areas of the user's back, so by opening different flip plates 21 in turn, different areas of the user's back can be exposed respectively, and at the same time, the unopened flip plates 21 can continue to play a supporting role, and combined with the mobile cleaning mechanism 3, the entire back of the user can be cleaned. In this process, there is no need to move the user, so the bathing bed of the present invention can greatly help disabled people to carry out cleaning work. The back of the user described in the present invention includes the entire back, legs and feet.

[0087] like Fig.16A and Fig. 16B As shown, at this time, the first flip plate 21a rotates to the vertical open position, and the second flip plate 21b, the third flip plate 21c and the fourth flip plate 21d are all in the horizontal closed position. Therefore, the area on the user's back corresponding to the first flip plate 21a near the right hand and the shoulder is exposed, and the cleaning mechanism 3 moves to the cleaning position corresponding to the area, so that the area on the user's back can be cleaned.

[0088] like Fig.17A and Fig. 17B As shown, at this time, the second flip plate 21b rotates to the vertical open position, and the first flip plate 21a, the third flip plate 21c and the fourth flip plate 21d are all in the horizontal closed position. Therefore, the area on the user's back corresponding to the second flip plate 21b near the left hand and shoulder is exposed, and the cleaning mechanism 3 moves to the cleaning position corresponding to the area, so that the area on the user's back can be cleaned.

[0089] like Fig.18A and Fig.18B As shown, at this time, the third flip plate 21c rotates to the vertical open position, and the first flip plate 21a, the second flip plate 21b and the fourth flip plate 21d are all in the horizontal closed position. Therefore, the area on the user's back close to the left leg and buttocks corresponding to the third flip plate 21c is exposed, and the cleaning mechanism 3 moves to the cleaning position corresponding to the area, so that the area on the user's back can be cleaned.

[0090] like Fig.19A and Fig.19BAs shown, at this time, the fourth flip plate 21d rotates to the vertical open position, and the first flip plate 21a, the second flip plate 21b and the third flip plate 21c are all in the horizontal closed position. Therefore, the area on the user's back corresponding to the fourth flip plate 21d near the right leg and buttocks is exposed, and the cleaning mechanism 3 moves to the cleaning position corresponding to the area, so that the area on the user's back can be cleaned.

[0091] Therefore, it can be known that when the first flip plate 21a, the second flip plate 21b, the third flip plate 21c and the fourth flip plate 21d are rotated to their vertical open positions respectively, the cleaning mechanism 3 can be moved to the cleaning position accordingly for cleaning. When all the flip plates 21 have been rotated to their vertical open positions once, the cleaning mechanism 3 can complete the cleaning of the entire back of the user. In this process, there is no need to move the user, nor to make him turn sideways or turn over, etc., so it can greatly facilitate the cleaning work of disabled people who are bedridden for a long time; in addition, when one of the flip plates 21 is opened for cleaning, the other flip plates are still in the closed position, that is, they can still support the user. Since the support area occupied by one flip plate 21 is only 1 / 4, only one flip plate 21 is rotated to open at a time, and the other flip plates 21 are in the closed position, which can ensure that the user is provided with safe support without worrying about the user falling over.

[0092] It is understandable that the number of the flip plates 21 may be 6 or more, and the present invention is not limited to this.

[0093] like Figure 9-Figure 15 As shown, the cleaning mechanism 3 includes a cleaning head 34 and a first driving mechanism 31 connected to the cleaning head 34. The first driving mechanism 31 is connected to the outer frame 1 and is used to move the cleaning head 34 along the height direction of the outer frame 1 (such as Figure 2 When the flip plate 21 is in the vertical open position, the first drive mechanism 31 enables the cleaning head 34 to move upward along the height direction of the outer frame 1 to a cleaning position corresponding to the flip plate 21; when the flip plate 21 is in the horizontal closed position, the first drive mechanism 31 enables the cleaning head 34 to move downward along the height direction of the outer frame 1 to a storage position.

[0094] The first driving mechanism 31 is configured as a push rod mechanism, a hydraulic mechanism, a screw mechanism or a belt drive mechanism.

[0095] like Fig. 9 As shown, the first driving mechanism 31 is taken as a push rod mechanism for example.

[0096] The first driving mechanism 31 includes a lifting push rod 311, a lifting bracket 312, a first slide rail 313 and a first slider 314. A cleaning mechanism bracket 14 is provided at the bottom of the outer frame 1, and the lifting push rod 311 can be fixed on the cleaning mechanism bracket 14.

[0097] The lifting push rod 311 is connected to the lifting bracket 312. Specifically, the number of the lifting push rods 311 can be 4. The four lifting push rods 311 respectively support the lifting bracket 312 at the four corners of the bottom of the lifting bracket 312. Therefore, when the lifting bracket 312 is lifted, the lifting bracket 312 can rise and fall stably.

[0098] In addition, the outer frame 1 is further provided with a first slide rail 313, which extends in the height direction of the outer frame 1. A first slider 314 is slidably provided on the first slide rail 313, and the first slider 314 is connected to the lifting bracket 312. When the lifting push rod 311 is extended, the lifting bracket 312 can be pushed to move on the first slide rail 313. The first slide rail 313 can ensure the moving track of the lifting push rod 311, so that the lifting push rod 311 can move more stably.

[0099] like Figure 7 As shown, the first driving mechanism 31 is located inside the outer frame 1 and below each flip plate 21. At this time, the cleaning head 34 above the first driving mechanism 31 will not contact the back of the user. Figure 8 As shown in FIG. 1 , when one of the flip plates 21, for example the first flip plate 21a, is rotated to a vertical open position, as shown in FIG. Fig. 9 and Fig.10 The first driving mechanism 31 can drive the cleaning head 34 to move upward until the cleaning head 34 can contact the back of the user, so as to clean the area on the back corresponding to the first flip plate 21a.

[0100] like Figure 7 As shown, the first driving mechanism 31 is located inside the outer frame 1 and below each flip plate 21. At this time, the cleaning head 34 above the first driving mechanism 31 will not contact the back of the user. Fig.18B As shown, when one of the flip plates 21, for example the third flip plate 21c, rotates to a vertical open position, the first driving mechanism 31 can drive the cleaning head 34 to move upward until the cleaning head 34 can contact the user's back, thereby cleaning the area on the back corresponding to the third flip plate 21c.

[0101] Therefore, it can be understood that the first driving mechanism 31 is used to adjust the height of the cleaning head 34 so that it moves upward to a cleaning position where it can contact the user, or moves downward to a storage position below the flip plate 21.

[0102] The cleaning mechanism 3 further includes a second driving mechanism 32 and a third driving mechanism 33, and the cleaning head 34 is connected to the first driving mechanism 31 via the second driving mechanism 32 and the third driving mechanism 33. The third driving mechanism 33 is connected to the cleaning head 34, and the second driving mechanism 32 is connected to the third driving mechanism 33 and the first driving mechanism 31 respectively. The second driving mechanism 32 is used to move the third driving mechanism 33 and the cleaning head 34 along the width direction of the outer frame 1, and the third driving mechanism 33 is used to move the cleaning head 34 along the length direction of the outer frame 1.

[0103] The second drive mechanism 32 is configured as a belt drive mechanism, a screw mechanism or a gear drive mechanism, and the third drive mechanism 33 is configured as a belt drive mechanism, a screw mechanism or a gear drive mechanism.

[0104] like Figure 11-Figure 15 As shown, the second driving mechanism 32 is a screw mechanism, and the third driving mechanism 33 is a belt transmission mechanism.

[0105] like Fig.11 , Fig.14 and Fig.15 As shown, the second driving mechanism 32 includes a slide, and the slide includes a slide bracket 321, a second slide rail 322, a second slider 323, a screw motor 324, a screw 325 and a screw nut 326. The slide 321 is arranged on the lifting bracket 312, so that when the lifting bracket 312 is lifted or lowered, the second driving mechanism 32 can be driven to be lifted or lowered together.

[0106] The second slide rail 322 and the screw rod 325 are arranged side by side on the slide table 321. The screw rod 325 is provided with a nut 326. The lower side of the nut 326 is fixedly connected to the second slider 323, and the lower end of the second slider 323 is movably arranged on the second slide rail 322. The nut 326 at the upper end of the second slider 323 is connected to the third driving mechanism 33. The end of the screw rod 325 is connected to the screw motor 324. When the screw motor 324 drives the screw rod 325 to rotate, the second slider 323 thereon moves on the screw rod 325, thereby driving the third driving mechanism 33 and the cleaning head 34 to move. The second slide rail 322 can constrain the moving trajectory, thereby ensuring that they move stably.

[0107] Since the second slide rail 322 and the screw rod 325 both extend along the width direction of the outer frame 1, when the screw rod 325 is driven to rotate, the nut 326 thereon can drive the third driving mechanism 33 and the cleaning head 34 to move along the extension direction of the screw rod 325, that is, the width direction of the outer frame 1.

[0108] A second limit device can be provided on the second slide rail 322 or the screw rod 325, which is used to limit the maximum displacement of the nut 326 (or the second slider 323). When the nut 326 (or the second slider 323) moves to its maximum displacement, the second limit device is triggered, which sends a signal to the screw motor 324. After receiving the signal, the screw motor 324 stops rotating, thereby stopping driving the nut 326 (or the second slider 323) to continue moving.

[0109] Therefore, it can be understood that the second driving mechanism 32 is used to adjust the position of the cleaning head 34 in the width direction of the outer frame 1, that is, the second driving mechanism 32 can move the cleaning head 34 from the position corresponding to the first flip plate 21a to the position corresponding to the second flip plate 21b, and vice versa. Therefore, when the first flip plate 21a rotates to the vertical open position, the second driving mechanism 32 can move the cleaning head 34 to the position corresponding to the first flip plate 21a, so as to clean the corresponding area of ​​the user's back; after the cleaning is completed, the first flip plate 21a rotates to the horizontal closed position, and the second flip plate 21b rotates to the vertical open position, then the second driving mechanism 32 can move the cleaning head 34 to the position corresponding to the second flip plate 21b, so as to clean the corresponding area of ​​the user's back.

[0110] Or the second driving mechanism 32 can move the cleaning head 34 from the position corresponding to the third flip plate 21c to the position corresponding to the fourth flip plate 21d, and vice versa. Therefore, when the third flip plate 21c rotates to the vertical open position, the second driving mechanism 32 can move the cleaning head 34 to the position corresponding to the third flip plate 21c, so as to clean the corresponding area of ​​the user's back; after cleaning, the third flip plate 21c rotates to the horizontal closed position, and the fourth flip plate 21d rotates to the vertical open position, then the second driving mechanism 32 can move the cleaning head 34 to the position corresponding to the fourth flip plate 21d, so as to clean the corresponding area of ​​the user's back.

[0111] The number of the second driving mechanisms 32 may be 2 or more. Fig. 6A As shown, the number of the second driving mechanisms 32 is two, which are spaced apart in the length direction of the outer frame 1 , so as to ensure better support for the third driving mechanism 33 .

[0112] like Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, the third driving mechanism 33 includes a synchronous belt 331 , a synchronous pulley 332 , a synchronous belt motor 333 , a slide bracket 334 , a third slide rail 335 and a third slider 336 .

[0113] The synchronous pulleys 332 are respectively arranged at both ends of the synchronous belt 331, and the rotation of the synchronous pulleys 332 can move the synchronous belt 331. More specifically, the synchronous pulleys 332 are gear structures with teeth, and the inner side of the synchronous pulleys 332 has corresponding teeth, so the synchronous pulleys 332 can mesh with the inner side of the synchronous belt 331, thereby driving it to move.

[0114] The synchronous pulley 332 is supported on the nut 326 of the second driving mechanism 32 through the slide bracket 334 , so when the nut 326 moves, the third driving mechanism 33 can be driven to move as a whole.

[0115] There may be two or more third sliders 336, each of which is connected to one side of the synchronous belt 331, so as to drive the third slider 336 to move. The third slider 336 is disposed on the third slide rail 335 and can move on the third slide rail 335, and the third slide rail 335 can constrain its moving trajectory. The third slider 336 is connected to the cleaning head 34, so that when it moves on the third slide rail 335, it can drive the cleaning head 34 to move together.

[0116] It can be understood that when the synchronous pulley 332 rotates, the synchronous belt 331 can drive the third slider 336 and the cleaning head 34 to move in the direction toward the user's head. When the synchronous pulley 332 rotates in the opposite direction, the synchronous belt 331 can drive the third slider 336 and the cleaning head 34 to move in the direction toward the user's feet.

[0117] Since the synchronous pulleys 332 are arranged at intervals in the length direction of the outer frame 1, that is, the synchronous belt 331 extends along the length direction of the outer frame 1, when the third slider 336 connected to the synchronous belt 331 moves, it can drive the cleaning head 34 to move along the length direction of the outer frame 1.

[0118] In addition, a limiting device is also provided on the synchronous pulley 332. The limiting device may be, for example, a mechanical limiting device or an electronic limiting device, which is used to stop the synchronous pulley 332 from rotating when the third slider 336 moves to the extreme position, thereby ensuring a safe distance between the third slider 336 and the synchronous pulley 332.

[0119] like Fig.12 As shown, the cleaning head 34 includes a cleaning bracket 341 and a brush head 342. The cleaning bracket 341 is respectively connected to two third sliders 336. The brush head 342 is arranged above the cleaning bracket 341 for brushing the back of the user. The cleaning bracket 341 is connected to the third slider 336, that is, the cleaning head 34 is supported on the third slider 336 through the cleaning bracket 341, so when the third slider 336 moves, the cleaning head 34 can be driven to move as a whole.

[0120] At least one brush head 342 is provided on the cleaning bracket 341. Fig.13 As shown, three brush heads 342 are provided on the cleaning bracket 341, and the three brush heads 342 can be connected to their respective motors to drive each brush head 342 to rotate independently, or the three brush heads 342 can be connected to the same motor to drive each brush head 342 to rotate together. It can be understood that more brush heads 342 can be provided on the cleaning bracket 341.

[0121] In some optional embodiments, an infrared sensing device can be provided on the brush head 342. When it detects contact with the user's back, it can send a signal to the lifting push rod 311 of the first driving mechanism 31. After receiving the signal, the lifting push rod 311 of the first driving mechanism 31 will stop driving the lifting bracket 312 to rise.

[0122] In some optional embodiments, a first limit device is provided on the first slide rail 313 or the outer frame 1 to limit the maximum displacement of the first slider 314. Since the brush head 342 is used to clean the back of the user, the height of the brush head 342 moving from the storage position to the cleaning position is certain, so the first limit device can be provided at the corresponding height position of the first slide rail 313 or the outer frame 1 to ensure the maximum displacement of the first slider 314, and when the first slider 314 moves to this position, the first limit device is triggered, which sends a signal to the lifting push rod 311 of the first driving mechanism 31, and after receiving the signal, the lifting push rod 311 of the first driving mechanism 31 stops driving the lifting bracket 312 to rise.

[0123] In addition, a nozzle can be provided in the brush head 342, through which cleaning water and cleaning liquid can be sprayed to the user, so that the cleaning can be more thorough. The nozzle can be connected to a water pump in the outer frame 1, and the cleaning water and cleaning liquid can be pumped to the nozzle through the water pump.

[0124] In some optional embodiments, the cleaning mechanism 3 can take corresponding movement actions according to whether each flip plate 21 is open. In this scheme, an induction switch (for example, a contact switch) can be set at a position corresponding to each flip plate 21 on the second beam 12. When a flip plate 21 rotates to a vertical open position, the corresponding induction switch is triggered, and the signal that the flip plate 21 is opened is sent to the cleaning mechanism 3. The first drive mechanism 31, the second drive mechanism 32 and the third drive mechanism 33 in the cleaning mechanism 3 perform corresponding actions, so that the cleaning mechanism 3 can be moved to the position corresponding to the opened flip plate 21 to perform the cleaning action. When each flip plate 21 is in a horizontal closed position, the corresponding induction switch is not triggered, and the cleaning mechanism 3 does not receive the signal that the flip plate 21 is opened, so the cleaning mechanism 3 will not move to the cleaning position.

[0125] Therefore, it can be understood that in this solution, whether the flip plate 21 at a certain position is opened can be set as needed, so that the area corresponding to the flip plate 21 can be cleaned intensively.

[0126] In some other optional embodiments, the cleaning mechanism 3 can move according to a prescribed moving route. For example, the cleaning mechanism 3 first moves to the cleaning position corresponding to the first flip plate 21a to perform the cleaning action, and then moves to the cleaning position corresponding to the second flip plate 21b to perform the cleaning action; then moves to the cleaning position corresponding to the third flip plate 21c to perform the cleaning action; finally, moves to the cleaning position corresponding to the fourth flip plate 21d to perform the cleaning action. When the cleaning actions at the above four positions are all completed, it can return to the storage position.

[0127] In addition, the first drive mechanism 31, the second drive mechanism 32 and the third drive mechanism 33 do not operate at the same time, that is, each drive mechanism adjusts the relative position of the cleaning head 34 and the outer frame 1 respectively to ensure safety. Therefore, when the lifting push rod 311 of the first drive mechanism 31 operates, the screw motor 324 of the second drive mechanism 32 and the synchronous pulley 332 of the third drive mechanism 33 are both in a locked state; similarly, when the screw motor 324 of the second drive mechanism 32 or the synchronous pulley 332 of the third drive mechanism 33 operates, the lifting push rod 311 of the first drive mechanism 31 is in a locked state.

[0128] In addition, if Figure 2 As shown, one or more universal wheels 13 are respectively arranged at the four corners of the bottom of the outer frame 1, and the outer frame 1 can be easily pushed into a room suitable for bathing through the universal wheels 13, so that the user on it can be cleaned.

[0129] According to a second aspect of the present invention, the present invention further provides a method for intelligently washing the back of a bathing bed for intelligently washing the back as described above, comprising the following steps:

[0130] 100: One of the flip plates 21 rotates relative to the outer frame 1 to a vertical open position.

[0131] 200: The cleaning mechanism 3 moves to the cleaning position corresponding to the flip plate 21 and performs the back cleaning operation.

[0132] 300 : Repeat step 100 until the cleaning mechanism 3 completes the back cleaning action at the cleaning position corresponding to each flip plate 21 .

[0133] 400: The cleaning mechanism 3 moves to the storage position.

[0134] 500: All the flip plates 21 rotate relative to the outer frame 1 to a horizontal closed position.

[0135] In a specific implementation, please refer to Figures 16A-19B , and please combine Figure 1 and Figure 7 In the initial state, the first flip plate 21a, the second flip plate 21b, the third flip plate 21c and the fourth flip plate 21d are all in a horizontal closed position. The user lies flat on each flip plate 21. It can be understood that the user's back is divided into four areas by each flip plate 21. In the initial state, the cleaning mechanism 3 is located inside the outer frame 1 and is in a storage position.

[0136] like Fig.16A and Fig. 16B As shown, first rotate the first flip plate 21a to the vertical open position. Figure 5 The flip driver 23 corresponding to the first flip plate 21a extends, thereby pushing the arc-shaped connecting plate 22 connected thereto to extend from between the first beam 11 and the second beam 12, and the upper end of the arc-shaped connecting plate 22 and the first flip plate 21a are connected by the pivot axis c. 1 The first flip plate 21a rotates relative to the rotation axis. 1 The rotation axis rotates relative to the second beam 12, that is, the first flip plate 21a can rotate from Figure 1 Rotate to the horizontal closed position shown Fig.16A and Fig. 16B Shown in upright open position.

[0137] like Fig. 16B As shown, after the first flip plate 21a rotates to the vertical open position, the first driving mechanism 31 is activated. The lifting push rod 311 extends to push the lifting bracket 312 to rise, and then the second driving mechanism 32, the third driving mechanism 33 and the cleaning head 34 on the lifting bracket 312 are lifted until the brush head 342 of the cleaning head 34 contacts the back of the user, so that the back of the user can be cleaned.

[0138] During cleaning, the screw motor 324 of the second driving mechanism 32 rotates forward or reversely, so that the screw nut 326 drives the third driving mechanism 33 and the cleaning head 34 to move on the second slide rail 322, thereby adjusting the position of the cleaning head 34 in the width direction of the outer frame 1. And through the forward or reverse rotation of the synchronous pulley 332 of the third driving mechanism 33, the third slider 336 drives the cleaning head 34 to move on the third slide rail 335, thereby adjusting the position of the cleaning head 34 in the length direction of the outer frame 1, so that the cleaning head 34 can clean various parts of the back area of ​​the user corresponding to the first flip plate 21a.

[0139] In one embodiment, the storage position of the cleaning mechanism 3 corresponds to the bottom of the first flip plate 21a, so after the first flip plate 21a rotates to the vertical open position, the first driving mechanism 31 can first drive the second driving mechanism 32, the third driving mechanism 33 and the cleaning head 34 to rise.

[0140] It is understandable that the storage position of the cleaning mechanism 3 can also be other positions. In this case, it is necessary to make the second driving mechanism 32 and / or the third driving mechanism 33 first drive the cleaning head 34 to move to the bottom of the opened flip plate 21, and then the first driving mechanism 31 drives the second driving mechanism 32, the third driving mechanism 33 and the cleaning head 34 to rise.

[0141] When the area corresponding to the first flip plate 21a is cleaned, the first flip plate 21a is rotated to a horizontal closed position. Figure 5 , the flip driver 23 corresponding to the first flip plate 21a retracts, thereby pushing the arc-shaped connecting plate 22 connected thereto back from between the first beam 11 and the second beam 12, and the upper end of the arc-shaped connecting plate 22 and the first flip plate 21a are pivoted at the pivot axis c 1 The first flip plate 21a rotates relative to the rotation axis. 1 The rotation axis rotates relative to the second beam 12, that is, the first flip plate 21a can rotate from Fig.16A and Fig. 16B The vertical open position shown is rotated to Figure 1 The horizontal closed position is shown.

[0142] like Fig.17A and Fig. 17B As shown, after the first flip plate 21a is rotated to the horizontal closed position, the second flip plate 21b is rotated to the vertical open position. The rotation method is the same as that of the first flip plate 21a, which will not be repeated here.

[0143] When the second flip plate 21b rotates to the vertical open position, the screw motor 324 of the second drive mechanism 32 rotates, so that the nut 326 drives the third drive mechanism 33 and the cleaning head 34 to move on the second slide rail 322. The cleaning head 34 can move from the cleaning position corresponding to the first flip plate 21a to the cleaning position corresponding to the second flip plate 21b and perform the cleaning action.

[0144] During cleaning, the second driving mechanism 32 and the third driving mechanism 33 are used to adjust the position of the cleaning head 34 in the width and length directions of the outer frame 1, so that the cleaning head 34 can clean various parts of the user's back area corresponding to the second flip plate 21b.

[0145] When the area corresponding to the second flip plate 21 b is cleaned, the second flip plate 21 b is rotated to a horizontal closed position.

[0146] like Fig.18A and Fig.18B As shown, after the second flip plate 21b is rotated to the horizontal closed position, the third flip plate 21c is rotated to the vertical open position. The rotation method is the same as the rotation method of the first flip plate 21a, which will not be repeated here.

[0147] When the third flip plate 21c rotates to the vertical open position, the synchronous pulley 332 of the third driving mechanism 33 rotates, so that the third slider 336 drives the cleaning head 34 to move. The cleaning head 34 can move from the cleaning position corresponding to the second flip plate 21b to the cleaning position corresponding to the third flip plate 21c and perform the cleaning action.

[0148] During cleaning, the second driving mechanism 32 and the third driving mechanism 33 are used to adjust the position of the cleaning head 34 in the width and length directions of the outer frame 1, so that the cleaning head 34 can clean various parts of the user's back area corresponding to the third flip plate 21c.

[0149] When the area corresponding to the third flip plate 21 c is cleaned, the third flip plate 21 c is rotated to a horizontal closed position.

[0150] like Fig.19A and Fig.19B As shown, after the third flip plate 21c is rotated to the horizontal closed position, the fourth flip plate 21d is rotated to the vertical open position. The rotation method is the same as that of the first flip plate 21a, which will not be repeated here.

[0151] When the fourth flip plate 21d rotates to the vertical open position, the screw motor 324 of the second drive mechanism 32 rotates, so that the nut 326 drives the third drive mechanism 33 and the cleaning head 34 to move on the second slide rail 322. The cleaning head 34 can move from the cleaning position corresponding to the third flip plate 21c to the cleaning position corresponding to the fourth flip plate 21d and perform the cleaning action.

[0152] During cleaning, the second driving mechanism 32 and the third driving mechanism 33 are used to adjust the position of the cleaning head 34 in the width and length directions of the outer frame 1, so that the cleaning head 34 can clean various parts of the user's back area corresponding to the fourth flip plate 21d.

[0153] After the cleaning head 34 cleans the back areas of the user corresponding to the above four flip plates 21, the first driving mechanism 31 can drive the second driving mechanism 32, the third driving mechanism 33 and the cleaning head 34 to descend, and the second driving mechanism 32 and the third driving mechanism 33 adjust the position of the cleaning head 34 in the width and length directions of the outer frame 1, so that it returns to the storage position under the first flip plate 21a, thereby ending the cleaning work.

[0154] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
